If hardness leakage is excessive after regeneration, which action is most appropriate?

• A. Immediately Start The Rinse Stage
• B. Check The Media Level And Then Redo The Backwash Cycle
• C. Re-Run The Regenerative Stage
• D. Shut The Unit Down And Check The Media Level

Answer: (D)

Hardness leakage after regeneration usually signals a problem with the resin bed’s position or height. If the bed isn’t at the correct level or has become uneven, water can bypass resin or channel through, allowing hardness to pass into the softened water. The best immediate action is to shut the unit down and check the media level. By inspecting the bed height and distribution, you can determine if resin needs topping up or redistribution to restore proper contact and regeneration efficiency. Once the bed is at the correct level, you can restart with the appropriate steps (such as rechecking bed expansion during backwash) to correct the leakage. Starting the rinse, re-running regeneration, or rushing backwash without first confirming the resin level won’t address the underlying issue and can waste resin and water.
